Troubleshooting
Fix common issues with models, project files, connected apps, and updates.
Models aren't working
- Make sure you're signed in, or that your custom service has a valid API key saved.
- Open Settings → Model Services, refresh the model list, and check that the model is enabled.
- For local models, confirm the local service is running and its address is reachable.
Files can't be read or modified
- Confirm the current conversation is linked to the correct project folder.
- Check whether the file is locked by another program and whether your user account has permission to act on it.
- For write operations, review and approve the permission request Nexts shows.
Connected apps fail
- Check that the connected service is running.
- Redo the sign-in authorization and confirm the requested permission scope.
- For remote MCP services, verify the address, the network, and the trustworthiness of the service.
